REED.

Application filed August 31, 1927.

My invention relates to reeds and more particularly to a reed structure for voice mechanism for talking dolls, and, it is a distinct and practical improvement to overcome certain practical objections to, and defects in the present type of reeds employed 1n voice mechanisms.

Another object of the invention is the provision of a reed structure for voice mechanism for talking dolls which possesses advantages in points of simplicity and efficiency, and, at the same time proves itself comparatively inexpensive in cost of manufacture.

lVith the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the seyeral views I Fig. 1, is a sectional view of an air expelling member of a voice mechanism showing my reed applied thereto.

In carrying out the aim of my present invention, I employ a flat metallic disk 1 which is adapted to act as a closure for the open end of sound chamber 2 within the body of an air expelling member 3, which sound chamber 2 communicates with a sound outlet opening 4i, such as used in connection with collapsible bellows used in Voice mechanism for talking dolls.

The flat disk 1, which may be of any desired shape in outline, is provided with a straight channel 5 of the desired depth and Serial No. 216,541.

length which is formed by pressing the metal toward and beyond the inner face of the disk. The disk 1 at one end of the channel is provided with a cutaway portion, or opening 6 to provide an open end for the channel for emitting air into the sound chamber of the air expelling member from the channel. The disk 1 is also provided upon its inner face at the marginal edge of the depressed portion of the disk forming the air channel 5, with the exception of the open end thereof, with a. channel 7 to provice a raised tl-shaped seating surface 8 upon the outer faceof the disk 1 and which seating surface S disposed above the plane of the outer face of the disk 1. The seating surface 8 is curved trans versely so that there will not be a flat face for tlie reed to engage. This prevents any sound produced from being suddenly choked. The raised seating surface 8 is provided with a slightly inclined section 9 extending from its open end to points located approximately adjacent the center of the disk 1 and then provided with the slightly curved section 10 from these points to the curved end of the raised seating surface. Thus, the seat is not parallel with the outer face of the disk 1.

Mounted upon the outer face of the disk 1 is a reed member having a head section 11 of the same size and contour as one end of the disk 1 and which terminates in a vibratory tongue section 12 adapted to normally engage the inclined section 9 of the raised U- shaped seating surface 8 which partially surrounds the channel 5.

Mounted upon the head section 11 of the reed member which is made of relatively thin metal, is a metallic plate 13 of the same size and contour as the head section 10 of the reed member and as one end of the disk 1.

lVhen the disk 1, reed member and plate are assembled one upon the other, a pair of radially directed arms designated 14 forming a part of the disk 1 are folded over and inwardly to clinch the outer face of the plate 13 for clamping the vibratory tongue section of the reed member in position over the channel 5 and holding the head portion thereof against displacement between the disk 1 and the plate 13.

In operation, air being compressed within a bellows by an air expelling member provided with the reed mechanism, is forced between the vibratory tongue 12 of the reed member and its raised slightly curved portion 10 of the seating surface 8 into the channel 5 thereby vibrating the tongue 12 for producing a sound within the sound chamber 2 of the air expelling member 3 from where it is emanated through the sound outlet opening 4.

The fact that the thin reed member is flat and straight and the raised seating surface 8 is curved transversely and slightly curved longitudinally as at 10 prevents sudden blasts of air from choking the sound produced by the reed as the air will follow the curved outer face of the seating surface 8, thus having a lifting or vibratory effect upon the reed rather than a choking effect which is caused by the reed hugging tightly its seat and prevent the air wanting to escape from the bellows finding its way into the channel 5 between the seating surface 8 and the \'ibratory tongue 12 of the reed member.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device for this purpose has been disclosed, but it is to be understood that I do not desire to restrict, or limit myself to the very details of the construction shown and described, which is merely illustrative, it being obvious that changes, not involving the exercise of invention may be made without conflicting or departing from the spirit of the invention Within the scope of the appended claims.

What I claim is:

1. In a reed for voice mechanism, a flat metallic disk provided with a channel having an open end, said disk having an opening at the open end of said channel, a seating surface at the edge of the channel, said seating surface being disposed above the plane of the disk, a reed member including a vibratory tongue section mounted upon the disk with the tongue section engaging the seating surface, a plate mounted upon the reed member beyond the vibratory tongue section thereof and arms integral with and extending from the edge of the disk clinchable upon said plate for securing the reed member against displacement between the disk and plate.

2. In a reed structure, a disk having a channel formed therein open atone end, said disk having an opening at the open end of said channel, a U-shaped convexed seating surface at the edge of said channel which is disposed above the plane of the disk, a flat reed member including a vibratory tongue section mounted upon said disk with the tongue section spanning the channel and the remainder of the reed member covering the opening and means integral with and extending from the edge of the disk for securing said reed member against displacement upon said disk.

3. In a reed structure, a fiat circular metallic disk having a channel therein open at one end and having an opening opposite the open end of the channel, a U-shaped seating surface at the edge of said channel, said seating surface being curved transversely and having a longitudinally inclined portion and a longitudinally curved portion disposed above the plane of the disk, a pair of tongues directed radially from the edge of the disk, a flat metallic reed member including a vibratory tongue section mounted upon said disk with the tongue section spanning the channel and in engagement with the inclined portion of the seating surface, a plate seated upon the non-vibratory section of the reed member and the radially directed tongues of the disk being clinchable upon said plate for holding the reed member against displacement upon the disk.

In testimony whereof, I have hereunto affixed my signature.
